vintage kodak vr35 k12 ektar lens 35mm camera with lithium power pack. the battery does not seem to shut all the way. however, it does stay closed, see picture. The camera worked, but a regular 9 volt battery does not take up the whole battery compartment. There is empty space on the sides and between the battery and battery door. With the battery door open, I had to hold the battery in place for the camera and flash to work.
